In the winter when doing a lot of work on my table saw, I turn off all
spark producing devices, as dust like volatile liquids can explode
with an ignition source and the right concentration.Â* With saw
dust
the chances of explosion are extremely low.Â* But the chances of one
house blowing up from a gas leak are extremely low.

It's been a long time since I've seen the saw dust explosion
thing... IIRC,
it takes a dust to air ratio so thick that you can't breath.

I don't recall if the warning to ground the DC is to prevent an
explosion from a spark or not.

More likely to prevent one from being shocked from static electricity
on
the hose.Â* And that static electricity tends to let dust build up inside
the hose.

The grounding strap in the hoses helps to prevent clogs, keeps things
from sticking to each other.

this is a refference for my message on dust explosions

My frist post appears not to have come through.

Static electricity causes the dust in your dust colllection system to
stick together and clog up the pipes. The electicity is bleed from the
system to the ground by the metal grounding strap.

This is the same electicity that you see sometime in cat fur, or when
you touch your spouse's noise

It is a common cause of explosions in grain elevators, which were quite
common in the past,
